Load Indicator Lights
The load indicators are the external red and green lamps on each side of the truck. In addition, the red and green light emitting diodes (LED) on the POD indicate the status of the external loading lamps. These indicators inform the loader operator and the truck operator of the loading progress toward a target payload weight. The external lamps are active only during the loading cycle. The external lamps are off at all other times. Note: External load indicator lamps should light if a lamp test is initiated and the truck speed is less than 8.1 km (5 mph). During loading, the green (continue loading) lamps will be on until the payload is 95 percent of the setting for the target weight. Then, the red (stop loading) indicator lamp will light. The system may be setup for last loader pass indication. In this mode, the PMC internally calculates an average loader pass size and predicts payload weight after the next pass is to be applied. If the predicted weight after the next loader pass will be above 95 percent of the target weight setting, the red lamps are flashed (indicating the next loader pass should be the last pass). Note: The "last-pass" indicator will only work correctly in loading applications that require at least three loader passes after the truck has stopped for loading. If the first loader pass is used to spot the truck then a minimum of four loader passes are necessary for the "last-pass" indicator to work correctly.Cycle Data
Throughout the truck's haul cycle, several conditions are monitored. All data collected during each haul cycle is stored into memory for later downloading through the communications port using a laptop computer, 9X-3393 connecting cable, printer and WINTPMS software package, EERD3600. A TPMS haul cycle begins when the truck has dumped the previous payload and ends when the new payload has been dumped. The truck is considered empty from the time the payload has been dumped to the time when the truck stops empty at the loading site under the loader. Loading time and payload weights are monitored at the loading site. These values are measured in 1 second and .0907 tonnes (.1 us ton) units, up to 7200 seconds and 725.6 tonnes (800 us tons). The truck is considered loading from the time the truck stops empty at the loading site under the loader
